find 66 2/3 of 900


27 1/2% of 1200


17 1/2% of 1000

33 1/2% of 600​

Answers

9514 1404 393

Answer:

600330175201 (as written) 200 (if it should be 33 1/3%)

Step-by-step explanation:

The easiest way to do these is to make use of your knowledge of the decimal equivalents of fractions and percentages.

  66 2/3% of 900 = 2/3 × 900 = 600

  27 1/2% of 1200 = 0.275 × 1200 = 330

  17 1/2% of 1000 = 0.175 × 1000 = 175 . . . . move the decimal point

  33 1/3% of 600 = 1/3 × 600 = 200

     or 33 1/2% of 600 = 0.335 × 600 = 201

_____

Additional comment

The repeating decimal for 1/3 is 0.33333.... As a percentage, that is 33 1/3%. Then 2/3 = 66 2/3%.

To change a percentage to a decimal, divide it by 100%.

  17.5% = (17.5%)/(100%) = 17.5/100 = 0.175

__

The product 0.275 × 1200 can be rewritten as ...

  0.275 × 1200 = 0.275 × 1000 × 1.2 = 275 ×1.2 = 275 + 0.2×275

  = 275 +55 = 330

This is a calculation you can do in your head.

__

We suspect a couple of typos in your question. If you mean 66 2/3, not 66 2/3%, then multiply the first answer by 100 to get 60,000.

We have shown answers for both 33 1/2% as your problem says, and 33 1/3%, which would be the more usual fraction.

game?
A
15%
43%
C.

D
85%

Answers

The approximate percentage of the points scored during the second part of the  game is 43%

Given the total score at the second part of the game  = 35 points

Score at the first part of the game = 20 points

Amount of score during the second part of the game  = 35  = 20 = 15 points

% score in the second part  = 15/35 * 100

% score in the second part  = 1500/35

% score in the second part = 42.85 ≈ 43%

Hence the approximate percentage of the points scored during the second part of the  game is 43%
